Unconventional Success: A Fundamental Approach to Personal Investment

Summary

The bestselling author of Pioneering Portfolio Management, the definitive template for institutional fund management, returns with a book that shows individual investors how to manage their financial assets.

In Unconventional Success, investment legend David F. Swensen offers incontrovertible evidence that the for-profit mutual-fund industry consistently fails the average investor. From excessive management fees to the frequent "churning" of portfolios, the relentless pursuit of profits by mutual-fund management companies harms individual clients. Perhaps most destructive of all are the hidden schemes that limit investor choice and reduce returns, including "pay-to-play" product-placement fees, stale-price trading scams, soft-dollar kickbacks, and 12b-1 distribution charges.

Even if investors manage to emerge unscathed from an encounter with the profit-seeking mutual-fund industry, individuals face the likelihood of self-inflicted pain. The common practice of selling losers and buying winners (and doing both too often) damages portfolio returns and increases tax liabilities, delivering a one-two punch to investor aspirations.

About the Author

Preface

When I began my work on Unconventional Success, I contemplated writing a different book. My first volume, Pioneering Portfolio Management: An Unconventional Approach to Institutional Investment, drew on my years of experience as Yale University’s chief investment officer to provide a template for other institutions to use in managing their funds. Pioneering Portfolio Management describes an equity-oriented, broadly diversified, actively managed investment program. I expected that Unconventional Success would resemble Pioneering Portfolio Management, adjusting only for differences between the resources and instruments available to institutions and to individuals.

As I gathered information for my new book, the data clearly pointed to the failure of active management by profit-seeking mutual-fund managers to produce satisfactory results for individual investors. Following the evidence, I concluded that individuals fare best by constructing equity-oriented, broadly diversified portfolios without the active management component. Instead of pursuing ephemeral promises of market-beating strategies, individuals benefit from adopting the ironclad reality of market-mimicking portfolios managed by not-for-profit investment organizations.

The colossal failure of the mutual-fund industry carries serious implications for society, particularly regarding retirement security for American workers. I share with most economists the bias that free markets generally produce superior outcomes, believing that government intervention often creates more problems than it solves. However, the market failure resulting from the mutual-fund industry’s systemic exploitation of individual investors requires government action. Without an appropriate policy response, I worry about the level of resources available to support future generations of American retirees.

Introduction

John Maynard Keynes wrote, Worldly wisdom teaches that it is better for reputation to fail conventionally than to succeed unconventionally.¹ The profound wisdom of Keynes’s statement reaches into every nook and cranny of the investment world. Slavishly following conventional wisdom proves unwise, as the frequently trod path often leads to disappointment. Taking a well-considered unconventional approach generally proves sensible, as the less-traveled route provides greater opportunity for success.

Contrarian Investing

Pursuit of nontraditional strategies poses significant challenges for investors. Human nature prefers the comfort that comes with pursuing a time-honored strategy. Sharing a common outcome with large numbers of fellow citizens creates a mutually reinforcing social bond. Unfortunately, the comfortable rarely produces success.

Millions of mutual-fund investors sleep well at night, serene in the belief that superior outcomes result from pooling funds with like-minded investors and engaging high-quality investment managers to provide professional oversight. The conventional wisdom ends up hopelessly unwise, as evidence shows an overwhelming rate of failure by mutual funds to deliver on promises. A nontraditional approach leads to greater likelihood of investment success.

In the eyes of public opinion, the contrarian investor faces a lose-lose proposition. When contrarian approaches fail to keep pace with the current market darling, more-fashionable players mock the out-of-step independent thinker. When contrarian approaches surpass the alternatives, consensus-oriented players decry the irresponsibility of the unconventional investor. Regardless of the investment outcome, out-of-the-mainstream investors receive cold comfort from outside observers.

Contrarian investors require conviction to implement and maintain an unconventional portfolio. Without a rock-solid belief in the fundamental principles that undergird an intelligently crafted portfolio, weak-kneed investors face the likelihood of a disastrous whipsaw. By abandoning an unconventional strategy in the face of poor performance and implementing a conventional alternative after a run of strong investment results, investors sell low and buy high. At some point after the garden-variety investor abandons the unconventional, rationality prevails. The recently oh-so-attractive conventional alternative falters. The recently out-of-favor contrarian portfolio shines. Investors who sold low and bought high suffer the consequences.

In its most basic form, the message of Unconventional Success requires only a few pages to describe the blueprint of a well-diversified, equity-oriented, passively managed portfolio, using not-for-profit investment managers to implement the plan. Unfortunately, a prefabricated version of the recommended strategy provides scant assistance to time-constrained investors. Investment success requires the conviction that comes from a fundamental understanding of the rationale for building the portfolio to certain specifications. Unless investors truly believe in the efficacy and validity of an unconventional approach to asset management, the end result almost certainly fails to withstand the wear and tear of market forces.

Thoughtless, knee-jerk contrarian responses ultimately generate results as dismal as the conventional alternative. Consensus-driven strategies frequently produce attractive returns for extended periods of time, placing the fickle contrarian in a difficult position. Complicating the contrarian’s life, in some situations the consensus proves correct. Investment success requires far more than taking the other side of the market’s trade of the day. Thoughtful investors build investment programs on a fundamental understanding of the reasons for pursuing a nonconventional approach.

Unconventional Success seeks to provide investors with the knowledge and fortitude to take a contrarian path. Examples of the pitfalls that swallow mainstream investors teach lessons in what to avoid. Descriptions of less-traveled routes that beckon unconventional investors offer alternatives to consider. If understanding leads to conviction, then knowledge proves indispensable to investment success.

Public Policy Issues

Although the primary purpose of Unconventional Success concerns the description of a sensible investment framework for individuals, the book touches on important public policy issues central to the retirement security of American workers. Increasingly, individuals shoulder responsibility for accumulating the resources necessary to fund a comfortable retirement. In recent decades, employer-managed retirement programs gave way to employee-directed retirement schemes. The shift in accountability from employer to employee caused a move from reasonably well-managed, low-cost investment programs to generally poorly managed, high-cost investment programs. The increase in employee-directed retirement programs threatens the retirement security of millions of Americans.

The decline in employer-sponsored defined benefit programs seems irreversible. Employers dislike defined benefit plans, because of the large, variable liability associated with a promise to pay remainder-of-lifetime benefits to pensioners and because of the large, variable pool of assets required to fund the liability. Employees dislike defined benefit plans, because the future stream of pension payments lacks definition and immediacy. In popular opinion, defined benefit plans register as unpopular.

Unfortunately, defined contribution plans fail to make the grade. Some employees decline to participate. Other employees participate at levels insufficient to produce adequate retirement savings. When employees change jobs, far too many cash out and spend the proceeds. The voluntary nature of participation in defined contribution plans poses the first challenge to future retirement security.

High-cost investment alternatives pose the second threat to retirement security. Defined contribution menus reflect the investment products promoted by the mutual-fund industry. As a result, investors pay high fees for mediocre performance. The investment tools available to defined contribution participants fall far short of minimal standards of adequacy.

The third impediment to retirement security concerns the investment management expertise of the participants. Most individuals lack the specialized knowledge necessary to succeed in today’s highly competitive investment markets. Poor asset allocation, ill-considered active management, and perverse market timing lead the list of errors made by individual investors. Even with a massive educational effort, the likelihood of producing a nation of effective investors seems small.

One appropriate policy response to the retirement savings problem puts defined benefit programs at the center of an individual’s retirement program and places defined contribution programs on the periphery. Unfortunately, political sentiment seems to lean in the opposite direction. The Bush administration’s proposal to allow individuals to voluntarily invest a portion of their Social Security taxes in personal retirement accounts imposes an even greater responsibility on the individual investor.² Partial privatization of Social Security causes individuals to decide where to invest a portion of retirement assets, adding another obligation to the already-too-large burden on ill-equipped individual investors.

In all likelihood post-Bush ideology will permit future workers to withdraw part of their Social Security credits in private self-managed accounts. Why? Because that will work out well for the greatest numbers? No. It is virtually guaranteed to work out expensively for most people. But the finance industries will make out well, doing their usual mediocre job for their clients who have Social Security funds to invest. Lobbyists will grease the skids to favor a system with gratuitous deadweight losses and inefficiencies.³

Another appropriate policy response limits investment alternatives to a well-structured set of choices. Government-provided tax advantages encourage individual participation in defined contribution programs. Suppose the government were to award tax benefits only to accounts that invest in low-cost, market-mimicking funds. By restricting tax-advantaged investments to passive vehicles, investors face far fewer opportunities to make investment mistakes. Government regulation might address market-timing issues by limiting the number and frequency of moves between funds. Educational efforts might deal with the challenges of asset allocation, encouraging individuals to adopt investment programs that fit their specific risk profiles and time horizons. Acting in loco parentis, the government could create powerful incentives to adopt passively managed, appropriately allocated investment programs.

The U.S. government’s Thrift Savings Plan, developed for the country’s civilian and military employees, serves as a possible model. At the end of 2003, the plan contained $128.8 billion in assets distributed across five funds. Four of the funds track well-known indices, namely the large-capitalization-stock S&P 500 Index, the small-capitalization-stock Wilshire 4500 Index, the developed-foreign-stock MSCI EAFE Index and the broadly inclusive domestic bond Lehman Brothers U.S. Aggregate Index. From a security selection perspective, the U.S. government protects its employees from playing the negative-sum game of active management.

If tax-advantaged investments were limited to passively managed investment vehicles, investors might continue to pursue the futile game of high-cost active management with taxable funds. But the carrot of the government’s tax advantages would accompany the stick of limitations on investment choice, forcing investors to choose from among a high-quality set of alternatives and improving the retirement prospects for millions of Americans.

The mutual-fund industry sits at the center of a massive market failure. The asymmetry between sophisticated institutional providers of investment management services and unsophisticated individual consumers results in a monumental transfer of wealth from individual to institution. The case for government intervention rests on the clear inability of market mechanisms to produce satisfactory outcomes for the vast majority of individual investors.

Mutual-Fund Industry Failure

Unconventional Success concludes that the mutual-fund industry fails America’s individual investors. Compelling data show that nearly certain disappointment awaits the mutual-fund shareholder who hopes to generate market-beating returns. The root of the problem lies in the competition between a mutual-fund management company’s fiduciary responsibility and its profit motive. The contest almost inevitably resolves in favor of the bottom line. Individual investors lose. Mutual-fund managers win.

Evidence points overwhelmingly to the conclusion that active management of assets fails to produce satisfactory results for individual investors. Two factors explain the individual’s predicament. The first problem stems from the investment choices available to individuals. High costs and poor execution doom the vast majority of offerings. The second problem concerns responses by individuals to markets. Research shortcomings, rearview-mirror investing, and investor fickleness (in the face of both adversity and opportunity) cripple most investment programs. If the outside investment manager fails to diminish investor assets, then the investor steps in to administer self-inflicted pain.

A distressing tale results. Much of Unconventional Success details the shortcomings of the mutual-fund industry, warning investors to stay away from profit-driven investment management organizations. Another significant portion of the book describes the behavioral miscues of individuals, suggesting that investors create a plethora of problems for themselves.

Ultimately, Unconventional Success proposes a positive solution to the investments challenge facing individual investors. The investment management world includes a very small number of not-for-profit money management firms, allowing investors the opportunity to invest with organizations devoted exclusively to fulfilling fiduciary obligations. Moreover, the market contains a number of attractively structured, passively managed investment alternatives, affording investors the opportunity to create equity-oriented, broadly diversified portfolios. In spite of the massive failure of the mutual-fund industry, investors willing to take an unconventional approach to portfolio management enjoy the opportunity to achieve financial success.

OVERVIEW

Sources of Return

Capital markets provide three tools for investors to employ in generating investment returns: asset allocation, market timing, and security selection. Explicit understanding of the nature and power of the three portfolio management tools allows investors to emphasize the factors most likely to contribute to long-term investment goals and deemphasize the factors most likely to interfere with long-term goals. Establishing a coherent investment program begins with understanding the relative importance of asset allocation, market timing, and security selection.

Asset allocation refers to the long-term decision regarding the proportion of assets that an investor chooses to place in particular classes of investments. For example, an investor with a long time horizon may opt to place 30 percent of assets in domestic equities, 20 percent of assets in foreign equities, 20 percent of assets in real estate, 15 percent of assets in inflation-indexed bonds, and 15 percent of assets in conventional bonds. The asset-allocation decision represents an infrequently revisited set of targets that defines the benchmark against which investors measure investment results.

Market timing refers to deviations from the long-term asset-allocation targets. Active market timing represents a purposeful attempt to generate short-term, superior returns based on insights regarding relative asset class valuations. For example, an investor who believes that stocks represent good value and bonds represent poor value might temporarily move the domestic stock allocation from 30 percent to 35 percent of assets, while reducing the bond allocation from 15 percent to 10 percent of assets. The return—positive or negative—from overweighting stocks and underweighting bonds represents the return from active market timing. Passive market timing consists of inadvertent deviations from long-term targets caused by the action of market forces on the values of a portfolio’s various asset classes. Whether caused by an investor’s active decision or an investor’s passive indifference, market-timing returns result from deviations between hypothetical target portfolio returns and actual portfolio asset class returns.

Security selection refers to the method of construction of portfolios for each of the individual asset classes, beginning with the choice of passive or active management. Passive management, the baseline against which other options must be measured, involves replication of the underlying market. In the case of domestic equities, the S&P 500, the S&P 1500, the Russell 3000, and the Wilshire 5000 represent broad-based indices that provide reasonable definitions of the market and sensible alternatives for investors pursuing passive management. Active management involves making bets against the market, with the investor attempting to overweight attractively priced stocks and underweight expensively priced stocks. The returns resulting from the active manager’s deviations relative to the benchmark represent security selection returns.

Asset-allocation decisions play a central role in determining investor results. A number of well-regarded studies of institutional portfolios conclude that approximately 90 percent of the variability of returns stems from asset allocation, leaving approximately 10 percent of the variability to be determined by security selection and market timing. Another important piece of research on performance of institutional investors suggests that 100 percent of investor returns derive from asset allocation, relegating security selection and market timing to an inconsequential role.¹ Careful investors pay close attention to the determination of asset class targets.

Academic conclusions about the importance of asset allocation lead many students of markets to conclude that some immutable law of finance dictates the primacy of asset allocation in the investment process. In fact, the studies cited reflect investor behavior, not finance theory. Investors gain important insights into questions of portfolio structure through understanding the forces that place asset allocation in a starring role, while leaving security selection and market timing in the wings.

ASSET ALLOCATION

Asset-allocation decisions take center stage in most investor portfolios, because investors generally own portfolios broadly diversified within asset classes (mitigating the impact of security selection decisions) and investors generally maintain reasonably stable asset-class allocations (mitigating the impact of market-timing decisions).* With two of the three sources of return down for the count, asset allocation takes the prize as the last contender standing. Since long-term portfolio targets play such a powerful role in determining investment outcomes, sensible investors pay careful attention to establishing thoughtful asset-allocation structures.

Investment maven Charley Ellis observes that investors generally fail to spend the most time and the most resources on the most important investment decisions. Seduced by the appeal of security-trading decisions and the allure of market-timing moves, investors tend to focus on unproductive and expensive portfolio-churning activities. While hot stocks and brilliant timing make wonderful cocktail party chatter, the conversation-stopping policy portfolio proves far more important to investment success.

The essence of the process that leads to creation of viable portfolio targets involves knowledge of basic investment principles, definition of specific investment goals, and understanding of individual risk tolerances. Fundamental investment tenets provide the framework upon which investors build portfolios with the greatest probability of meeting investor needs. Clear articulation of goals defines the task that investors desire to accomplish, while explicit specification of risk preferences outlines the parameters within which investors sensibly operate. Investors armed with basic investment principles, well-defined goals, and reasonable self-awareness increase the likelihood of investment success.

FUNDAMENTAL INVESTMENT PRINCIPLES

Finance theory and common sense support three long-term asset-allocation principles—the importance of equity ownership, the efficacy of portfolio diversification, and the significance of tax sensitivity. Allocations to equity-like assets enhance portfolio characteristics as the superior returns expected from high-risk positions ultimately produce greater wealth. Commitments to a range of asset types that behave differently one from another improve portfolio attributes, as the reduced risk associated with broadly diversified portfolios ultimately produces more stable returns. Attention to the tax characteristics of asset classes and tax consequences of portfolio strategies strengthens portfolio results, as the improved after-tax returns ultimately produce more assets. The wealth-creating equity bias, the risk-reducing portfolio diversification, and the return-enhancing tax sensitivity combine to undergird the asset-allocation structure of effective investment portfolios.

Equity Bias

Finance theory posits that equity investors rightly expect returns superior to those expected by holders of less risky financial assets, albeit at the cost of higher levels of risk. Because equity owners get paid after corporations satisfy all other claimants, equity ownership represents a residual interest. As such, stockholders occupy a riskier position than, say, corporate lenders who enjoy a superior position in a company’s capital structure. In the case of marketable securities returns, reality matches theory, as over reasonably long periods of time stock returns exceed those of bonds and cash.

History tells us that equity markets produce handsome returns over long holding periods. Any number of sources provide high quality information on capital markets returns. Ibbotson Associates, founded by Yale scholar Roger Ibbotson, produces a widely used survey of returns covering the past seventy-eight years. Over the nearly eight-decade period from 1926 to 2003, U.S. stocks produced an annual compound return of 10.4 percent, U.S. government bonds returned 5.4 percent, and U.S. Treasury bills generated 3.7 percent. The 5.0 percentage point difference between stock and bond returns represents the historical risk premium, defined as the return to equity holders for accepting risk above the level inherent in bond investments.

Even apparently modest return differentials, operating over long periods of time, translate into staggering wealth differentials. During the seventy-eight years of the Ibbotson series, as shown in Table 1.1, one dollar invested in large-company stocks expanded 2,285 times, while bonds produced a 61 multiple, and cash, an 18 multiple. Small stocks demonstrated even more impressive results, as the 1925 dollar multiplied 10,954 times by 2003. Equity ownership beats holding bonds or cash, hands down.

Similar results can be found in Jeremy Siegel’s Stocks for the Long Run. The third edition of Siegel’s classic study of capital markets returns shows U.S. stocks producing an 8.3 percent per annum compound return over the two centuries spanning 1802 to 2001. In a hard-to-believe statistic, one dollar invested in the stock market at the outset of the nineteenth century, with all gains and dividends reinvested, grows to $8.8 million at the beginning of the twenty-first century!

Bonds generate less spectacular results. The compound annual return for long-term government bonds of 4.9 percent per annum proves sufficient to cause one dollar to produce a portfolio worth $14,000 after a two-century holding period. Predictably, bills bring up the rear. The 4.3 percent compound return causes a dollar to produce a mere $4,500 after two hundred years. Note that the risk premium of 3.4 percentage points in Siegel’s two-century study falls in the same neighborhood as the risk premium of 5.0 percentage points in Ibbotson’s seventy-eight-year study.

Historical evidence clearly points to a strong equity orientation for long-term investment programs. In fact, a superficial examination of the data might lead to the conclusion that investors should put all of their eggs in the equity market basket. However, a closer look at history illustrates the dangers of a single-asset-class concentration.

Diversification

The stock market crash of 1929 provides the most dramatic example of holding an undiversified portfolio. From the peak of small company stock prices in November 1928 to the trough in 1932, small stock investors suffered an excruciating 90 percent collapse in value. The depression-induced deflation slightly mitigated the purchasing power loss, bringing the price-level-adjusted decline to 88 cents on the dollar. Table 1.2 outlines the terrible tale.

The bear market and stagflation of the 1970s present another example of intolerably poor small-stock returns. In the bull market frenzy of the 1960s, small-stock prices peaked in December 1968, a full four years prior to the peak in large-stock prices. In a seemingly inexorable decline, small stocks fell nearly 60 percent by the time they reached the bottom in December 1974. Adding to the pain of the bear market, inflation reduced the purchasing power of a 1968 dollar to just 68 cents six years later. The combination of market action and inflation erosion produced a purchasing-power-adjusted loss of more than 70 percent. Undiversified investors paid the piper.

From a strictly financial perspective, diversification improves portfolio characteristics by allowing investors to achieve higher returns for a given level of risk (or lower risk for a given level of returns). Generations of economics students who learned that there ain’t no such thing as a free lunch may be surprised to discover that Nobel laureate Harry Markowitz called diversification one of the economic world’s rare free lunches. By diversifying, investors gain risk reduction without return diminution (or gain return enhancement without risk expansion).

Ultimately, the behavioral benefits of diversification loom larger than the financial benefits. Investors with undiversified portfolios face enormous pressures, both internal and external, to change course when the concentrated strategy produces poor results. In the 1930s, as small-stock dollars collapsed to dimes, and in the 1970s, as small-stock dollars shrank to 30 cents, investors declared no more and never again, sold their shares and invested in cash. Of course, the investors’ epiphany regarding the risk of small-stock investing came at an inopportune time. A dollar invested in small stocks in June of 1932 grew more than 100,000-fold by December 2003. Unfortunately, diversification provides no guarantee that investors will stay the course through adverse conditions. But, when only a portion of the portfolio suffers from dramatically adverse price moves, investors face a higher likelihood of riding out the storm.

Sensible individuals take care to distribute assets across a range of investment alternatives. The act of diversification provides a free lunch of enhanced returns and reduced risk, increasing the likelihood that an investor will stay the course in difficult market environments.

Investment Principles in Practice

In spite of nearly universal support among investment professionals for equity-oriented, well-diversified portfolios, market practice generally fails to reflect fundamental portfolio management precepts. Consider the average asset allocation of college and university endowments, which represent the best managed of institutional funds. Ten years ago, as portrayed in Table 1.3, domestic equities constituted nearly 50 percent of assets and domestic bonds more than 40 percent. With two asset classes accounting for almost 90 percent of assets, the portfolios flunk the test of diversification. With low-expected-return bonds and cash accounting for in excess of 40 percent of assets, the portfolios flunk the test of equity orientation. In the early 1990s, college and university endowment managers earned dismal grades.

Portfolios dominated by traditional marketable securities exhibit even less diversification than the bond and stock distinction suggests. Under many circumstances, changes in interest rates—one of the most important fundamental drivers of market returns—influence bonds and stocks in similar fashion. When rates rise, the harsh reality of bond math calls for prices to fall. When rates rise, the discount rate applied to future corporate earnings streams rises as well, causing stock prices to fall. The converse holds, too. College and university endowment porfolios of the early 1990s exposed nearly 90 percent of assets to a common determinant of financial market returns.

Stock and bond holdings prove most diversifying when inflationary expectations fail to match the subsequent reality. For instance, in an environment of unanticipated inflation, the fixed nominal claims of bondholders become worth less. In contrast, higher-than-expected levels of inflation increase the value of a stockholder’s residual claim on corporate assets. The converse holds, too. In short, only under unusual circumstances do holdings of stocks and bonds produce substantial diversification.

The 2003 portfolios of colleges and universities show scant progress relative to the 1993 versions. Domestic equity holdings in 2003 amounted to nearly 48 percent of the average endowment, hovering around the same level as the portfolio of a decade earlier. Fixed-income portfolios constituted nearly 30 percent of assets, representing more than a 10 percentage point decline from the 1993 allocation. Obviously, the 1993 to 2003 reduction in exposure to traditional marketable securities improved portfolio characteristics. Yet, in spite of increased allocations to diversifying assets, the 2003 endowment registered neither as particularly well diversified nor as adequately equity-oriented.

Contrast the experience of the broad group of colleges and universities with the best-endowed educational institutions. Harvard, Yale, Princeton, and Stanford lead the endowment world in size and led the endowment world with early adoption of well-diversified, equity-oriented portfolios. As early as 1993 the market-leading quartet allocated only 56 percent of assets to domestic marketable securities, relative to the excessive level of 89 percent for the more inclusive group of educational endowments. By 2003, as shown in Table 1.4, the leading universities further improved endowment diversification, reducing the domestic marketable security allocation to 32 percent, relative to the broader universe’s allocation of 77 percent.

Not only did the larger endowments exhibit greater diversification, they showed superior equity orientation as well. Fixed-income allocations for the four top endowments amounted to an average of 20 percent in 1993 and 15 percent in 2003, representing approximately one-half of the respective allocations of 41 percent and 29 percent for the broad group of colleges and universities.

The well-diversified, equity-oriented portfolios produced superior results. For the ten years ending June 30, 2003, Harvard, Yale, Princeton, and Stanford generated results that stood in the top 5 percent of the ranks of endowed institutions, far outpacing the returns of the average college or university. Real-world application of fundamental investment principles produces superior outcomes.

MARKET TIMING

Market timing fails to make an important contribution to institutional portfolio results, because investors quite sensibly show reasonable constancy in holdings of various asset types. Perhaps institutions avoid market timing because they understand the inconsistency inherent in making a speculative short-term bet against a carefully crafted long-term target portfolio. Or maybe investors keep to policy asset allocations because they recognize the futility of consistently making the relative asset class valuation assessments necessary for market-timing success, particularly when such assessments rely on a bewildering collection of unknowable economic and financial variables. Regardless of the reasons for underlying stability in portfolio allocations, market timing fails to make a major difference in institutional investment results.

The story differs for individual investors. The available evidence points to a pattern of excessive allocation to recent strong performers offset by inadequate allocation to recent weak performers. Possibly, investors allow inertia to drive portfolio allocations, with asset class weights flowing and ebbing with the relative rise and fall of markets. Or maybe investors actively chase yesterday’s winners while aggressively abandoning previous losers. The impact of market timing on individual investor portfolios generally falls into the negative category.

The relative insignificance of market timing stems from the behavior of investors, not from the precepts of finance theory. Consider the market-timing alternative to the generally reasonable behavior of sticking to long-term asset-allocation targets. If an investor pursued an exclusive strategy of day trading stock index futures, investment results for the portfolio would have nothing to do with asset allocation or security selection and everything to do with market timing. The lack of widespread frenetic trading by investors stems either from a general sensibility of the investing populace or from a Darwinian winnowing of the day traders’ ranks.

Perhaps the most frequent variant of market timing comes not in the form of explicit bets for and against asset classes, but in the form of passive drift away from target allocations. If investors fail to counter market moves by making rebalancing trades, portfolio allocations inevitably move away from the desired target levels. For example, if bonds show superior performance relative to stocks, the bond portfolio rises above target levels as the stock portfolio falls below. A rebalancing trade requires sales of the relatively strongly performing bonds to fund purchases of the relatively poorly performing stocks. Since few investors engage in systematic rebalancing activity, most portfolios wax and wane with the markets, subjecting the portfolio to a strange form of market timing. By pursuing a tack that overweights recent strong performers and underweights recent weak performers, investors reduce chances for investment success.

Overweighting assets that produced strong past performance and underweighting assets that produced weak past performance provides a poor recipe for pleasing prospective results. Strong evidence exists that markets exhibit mean-reverting behavior, a tendency for good performance to follow bad and bad performance to follow good. In markets

Reviews

The language was a bit flowery at times but the contents seem well-researched and systematically presented along with supporting data, which enhances credibility. The book presents a practical approach that the average person can employ in constructing their portfolio.
